摘要
介绍了保护层开采后综放面全煤巷道的锚梁网支护技术。在采动卸压后的松软破碎煤层巷道掘进中采用锚梁网支护,较好地控制了顶煤破碎、垮落和掘进工作面坍塌问题。
The paper introduced the bolt/beam/mesh support technology for full seam gateway of fully mechanized coal caving mining face after coal mining of protective seam. The main technical issues of the bolt/beam/mesh support in the soft broken seam gateway heading are to control and prevent top coal breaking, falling and caving. The technical measures used in the test have solved those above problems.
